A nurse in an emergency department is reviewing a client's ECG reading.
Which of the following findings should the nurse identify as an indication that the client has first-degree heart block?
Prolonged PR intervals.
Nondiscernible P waves.
More P waves than QRS complexes.
No correlation between P and QRS waves.
The Correct Answer is A
First-degree heart block is a type of atrioventricular (AV) block that involves the consistent prolongation of the PR interval (defined as >0.20 seconds) due to delayed conduction via the atrioventricular node.
This is seen on an ECG as a PR interval greater than 200 ms in length.
Choice B: Nondiscernible P waves are not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice C: More P waves than QRS complexes is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice D: No correlation between P and QRS waves is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
